Patient leaflet - Maraviroc 150 mg film-coated tablets
1. What maraviroc tablets are and what they are used for
Maraviroc tablets contain a medicine called maraviroc. Maraviroc belongs to a group of medicines called CCR5 antagonists. Maraviroc works by blocking a receptor called CCR5 which HIV uses to enter and infect your blood cells.
Maraviroc is used to treat Human Immunodeficiency Virus type-1 (HIV-1) in adults and adolescents weighing at least 30 kg.
Maraviroc must be taken in combination with other medicines which are also used to treat the HIV infection. These medicines are all called anti-HIV medicines or antiretrovirals.
Maraviroc, as part of combination therapy, reduces the amount of virus in your body, and keeps it at a low level. This helps your body to increase the CD4 cell count in your blood. CD4 cells are a type of white blood cell that are important in helping your body to fight infection.

Other possible side effects of combination therapy for HIV
People taking combination therapy for HIV may get other side effects.
Symptoms of infection and inflammation
People with advanced HIV infection (AIDS) have weak immune systems, and are more likely to develop serious infections (opportunistic infections). When they start treatment, the immune system becomes stronger, so the body starts to fight infections.
Symptoms of infection and inflammation may develop, caused by either:
- old, hidden infections flaring up again as the body fights them · the immune system attacking healthy body tissue (autoimmune disorders).
The symptoms of autoimmune disorders may develop many months after you start taking medicine to treat your HIV infection. Symptoms may include: · muscle weakness
weakness beginning in the hands and feet and moving up towards the trunk of the
body
- palpitations or tremor
- hyperactivity (excessive restlessness and movement).
If you get any symptoms of infection or if you notice any of the symptoms above: Ø Tell your doctor immediately. Don't take other medicines for the infection without your doctor's advice.
Joint pain, stiffness and bone problems
Some people taking combination therapy for HIV develop a condition called osteonecrosis. With this condition, parts of the bone tissue die because of reduced blood supply to the bone.
It is not known how common this condition is. You may be more likely to develop it: · if you have been taking combination therapy for a long time
- if you are also taking anti-inflammatory medicines called corticosteroids · if you drink alcohol
- if you have a very weak immune system
- if you are overweight.
Signs to look out for include:
- stiffness in the joints
- aches and pains (especially in the hip, knee or shoulder)
- difficulty moving.
If you notice any of these symptoms:
- Tell your doctor.
